.1 do not limit myself to a single coil about the dome or core, nor toany particular positions of the coils. They may be superposed upon eachother, placed side by side along the core, or in any other suitablemanner. Neither do I confine myself to a single battery or device forgenerating electricity; I propose sometimes to use separate batteriestor the separate wires.

also, at times, to combine the coil through the boiler or otherreceptacle, by starting a wire .I propose from the battery, coil itabout the core, and,

after passing oil, to connect it with one end ofthe receptacle, unitingthe other end of the receptacle, with the other pole of the may becombined 'as' follows:
